The confBUILDBIN macro is used to define the
location of the devtools/bin directory.
Normally, this macro will never have to be defined because the
default value is correct, but there might be a rare circumstance when
you will need to redefine it. If, for example, you need to move the
devtools/bin directory to a different path, or
rename it, you can do so like this:
Note that the value given to confBUILDBIN must be
either an absolute path or a path relative to the
obj directory (sendmail is
built inside the obj directory).
The confBUILDBIN macro sets the
BUILDBIN= line in Makefile.
Depending on your operating system, that line might or might not be
used. For Solaris 2.5, for example, it is used like this:
One use for confBUILDBIN can occur when you are
actively modifying the sendmail code, and it
becomes appropriate to maintain the source completely separate from
the normal distribution tree.
